      Hey sross - Which fix did you apply? The one in post 19 or post 27?

      I'm convinced something has changed on the Paypal side. My subscriptions were working flawlessly for over 3 years, then suddenly they stopped working. Nothing has changed on my server or vb installation. Very frustrating!!

      I'm waiting to hear the official VB response to this issue. I'm surprisded there isn't more discussion of this problem.

            Thank you for clarifying.

            I wasn't sure if that fix was permanent or not but right now.. any port in the storm will do. I checked to be sure that was the code was the same one I have in my template and have now added my website's info per post 19 to my PayPal account (there wasn't any url there btw). If it doesn't work I'll try dropping the "forum" part but for not I used http://www.(inserted my website name).com/forum/payment_gateway.php?method=paypal (our forum uses the default singular "forum")

            Fingers crossed... I'll update whether it works or not in a day or two. Thank you again. I truly appreciate the help.

              Yup the post #19 worked for me.

              I changed(in your template)
              <input type="hidden" name="notify_url" value="$vboptions[bburl]/payment_gateway.php?method=paypal" />
              to
              <input type="hidden" name="notify_url" value="http://www.mysite.com/forums/payment_gateway.php?method=paypal" />

              I also enabled IPN in my paypal profile settings then
              put in the same gateway address.
              http://www.mysite.com/forums/payment...?method=paypal

              that fixed it.

                I have spent considerable time investigating this issue, and it appears to be related to changes on Paypal's end of the Instant Payment Notification (IPN) system. (1) Paypal recently started sending email warnings to Paypal account holders when there are IPN failures, and (2) Paypal has recently started disabling accounts after there are too many failed IPNs. This means that the failures are not something new, but that just recently some people have started receiving the warning emails and Paypal has started disabling IPN after too many failures.

                If you are receiving the IPN failure emails or your payments seem to have stopped working, please do the following to troubleshoot:

                Important: These troubleshooting steps have been superseded by the newly revised troubleshooting steps found in post #69. Thanks!
                1. Check your Paypal IPN settings (in your Paypal account) and make sure that IPNs are not currently disabled. If they are disabled, then contact Paypal to get them re-enabled. You can check if IPNs are disabled by checking your IPN history and seeing if your recent IPN messages have a status of "disabled". (My Account => History => IPN History)
                2. Check your Paypal IPN settings and make sure your Notification URL is empty. This needs to be empty because (a) it is not necessary, since vBulletin sends Paypal the correct URL to send the IPN to along with the payment request. (This is the notify_url parameter in the subscription_payment_paypal template). (b) The other reason this needs to be empty, is that if you have your vBulletin URL there, then Paypal will send IPN messages for all of your Paypal transactions, not only the ones that originate from your vBulletin installation. This will eventually cause Paypal to disable IPN for your account due to the failed IPNs.
                3. Make sure your Forum URL is correct in your vBulletin settings. (vBulletin Options => Site Name / URL / Contact Details => Forum URL) It should be the URL to your forums, with no trailing slash (/).

                Another thing to note is when the transaction log in the Admin CP shows “failure” for a transaction, that does not mean that the Paypal IPN failed, it only means that the transaction was not a charge or a reversal.

                So, to the best of my knowledge, this the explanation for why some of you have started to see these failure emails. If any of you have more information on the issue, please let me know and I will continue to investigate.

                I will now attempt to address a few things:

                Originally posted by dm_fan View Post

                I've looked at the subscription logs in vB and at the IPN log in our paypal account. They both show that anytime any payment is made to our paypal account, paypal's IPN system is trying to send the notification to our vB server. If the payment is for our vB subscription, it gets validated right away (just like it should). If it's a non-subscription payment, the IPN fails because vB doesn't see a valid subscription. So paypal trys to sent the notification again and again and again, with the same failed result. Apparently this has been going on for years because I have a log full of failures going back to when we began the subscription option on our forums.

These inevitably always appear as 16 failures both ends and are indicated in the forum transaction log as invalid_subscriptionid. Does this mean I have to have the Paypal acouunt dedicated to forum subscriptions and nothing else? I think I'll have to ask Paypal about whether it is possible for the IPNs to be selective and only sent for subscription payments.
                If you remove the Notification URL in your Paypal account, this should be fixed, since Paypal will then only send IPN messages to vBulletin when specifically asked to do so. If you have your vBulletin URL in the Notification URL setting in Paypal, then all transactions will be sent to your vBulletin installation. See item #2 above.

The transaction log in vB admin CP shows all these retries as 'failures'. The interval between retries increasing from less than a minute to 24 hours, the last about 4 days after the first.
                Can you go to your IPN history and click the linked "Message ID" for one of the failed messages, and post the details found there? I specifically want to look at the Notification URL, the HTTP Status code, and the IPN Message found there.

                  I removed the Notification URL in my Paypal and got this warning: "You must enter a properly formatted URL into the Notification URL field in order to activate or deactivate Instant Payment Notification." It won't allow me to save my IPN settings without a URL.
                  So I removed the URL and chose the "Do not receive IPN messages" options, clicked Save, and got the same message.
                  So I clicked the Cancel button, which took me back to the original IPN page, and I clicked the "Turn off IPN" button, and had to confirm that I will no longer receive IPN messages from PayPal.

                  So where does that leave me? Will the vBulletin system still work?

You can check if IPNs are disabled by checking your IPN history and seeing if your recent IPN messages have a status of "disabled". (My Account => History => IPN History)
                    No failures listed.. not disabled.. It looks like all payments that were supposed to go through did so and yet I've gotten two of these msgs so far.

                    Check your Paypal IPN settings and make sure your Notification URL is empty. This needs to be empty because (a) it is not necessary, since vBulletin sends Paypal the correct URL to send the IPN to along with the payment request.

This will eventually cause Paypal to disable IPN for your account due to the failed IPNs.
                    I've taken the url back out again and tried to save it. Same msg as above poster and I can't take it out. Should I leave the IPN enabled or disabled? It's enabled ATM.
                    Make sure your Forum URL is correct in your vBulletin settings. (vBulletin Options => Site Name / URL / Contact Details => Forum URL) It should be the URL to your forums, with no trailing slash (/).
                    It didn't have the slash but it didn't have "www" in the url so I added that in. I don't know why I didn't have it in. I know it normally needs to be there. Could that have caused a problem?

                      I got another one of these msgs last night so having the url put in (http://www. mywebsite.com/forum/payment_gateway.php?method=paypal) and adding the www under Options didn't help. I'm now stuck because I can't save it as Enabled or even Disabled on PayPal w/o a url to send it to and the one I put in apparently isn't correct.

                      From what I've read on the PayPal site (HERE) it looks like I could turn it off but then I'd have to check PayPal every day to keep an eye on who has donated, etc.

                      Thanks in advance for any help.

                        If you have the Notifications URL set in your Paypal account, you will potentially have problems if you receive any payments that are not related to your vBulletin subscriptions, or if the vBulletin Notification URL were ever to change in the future. To fully remove the Notification URL from Paypal, (which I recommend you do), just turn IPN off in your Paypal account. This way you don't have a Notification URL hardcoded in your Paypal account, but since vBulletin sends an explicit Notification URL along with each transaction request, your vBulletin installation will still receive the notifications and work correctly. To turn IPN off in Paypal, go to My Account => Profile => More Options => Selling Preferences => Instant Payment Notification Preferences => Turn Off IPN.

                        Another note to those of you who are seeing Notification URLs that end in /subscriptions/paypal.php This was the URL for IPN in previous versions of vBulletin. The current URL is /payment_gateway.php?method=paypal (I believe it changed in v3.5.0).

                          and 2 were due to caqncellation of subscription by user after signing up for subscription and 1 was for non-vbulletin forum subscription.
                          so this error isnt danger zone accoridng to me, just misinterpretation from paypal..vbulletin guys shd look into it and release fix for it..paypal might have updated it's software which is causing such problems..

                              Have you already completed the three troubleshooting steps from post #52? If not, please try that.

                                So, David, it seems that your recommendation is to just turn the thing off completely. I went to my IPN history page and this is at the top: The IPN feature is turned off. You must turn on IPN in order to create history data.

                                If it's already off, then why am I still getting the notification/error messages sent from PayPal? I have no clue if subscriptions are going through or not...
                                Regards,
                                Nick
